1 Samuel 18:3-8

3And Jonathan made a solemn pact with David, because he loved him as he loved himself.

4Jonathan sealed the pact by taking off his robe and giving it to David, together with his tunic, sword, bow, and belt.

5Whatever Saul asked David to do, David did it successfully. So Saul made him a commander over the men of war, an appointment that was welcomed by the people and Saul’s officers alike.

6When the victorious Israelite army was returning home after David had killed the Philistine, women from all the towns of Israel came out to meet King Saul. They sang and danced for joy with tambourines and cymbals.

7This was their song: “Saul has killed his thousands, and David his ten thousands!”

8This made Saul very angry. “What’s this?” he said. “They credit David with ten thousands and me with only thousands. Next they’ll be making him their king!”
